Tool contract 7.1.16

• A member read (player_tag) says a sitting still being learned comes back in the next read with a running total under the same started_at, since a member read keeps no pointer: keep the newest (#302).
• The clan entry summary ends every capped list with +N: quiet, back, new bests, ranked and standout sessions. "back:" had named 3 of 12 returns and read as complete (#303).

Additive.
